help me guess my hp?
 

hey guys, anybody wanna help me guess my hp? I've had a couple educated guesses but they were kinda lop sided.
just wanted to see what you guys think.

heres a list of the mods:(its an 87 gt)

91 block bored .030 over, forged steel crank, manley rods, weisco pistons, FMS B303 cam, full double roller timing set, arp studs and bolts.

k&n air filter, C&L 73mm mass air meter, BBK 65mm TB, edelbrock performer RPM intakes(all port matched)

edelbrock performer RPM heads(2.02 intake 1.60 exhuast), HD dual valve springs, crane 1.6 roller rockers, crane hardened push rods, 24lb fuel injectors

MSD box, soft touch rpm control, crane PS91 coil, MSD 8.5mm wires, MSD cap and rotor.

JBA 1 5/8" headers, MAC h-pipe, flowmaster 2 chamber mufflers

FMS HD trans upgrade, FMS alum drive shaft, B&M ripper shifter, steeda adj cable and quadrant, FMS HD clutch assembly, richmond 3:73 gears

In the spring I plan on getting it into the shop and getting it chipped, tuned and dynoed to get some exact #'s.

Thanks in advance fo the help

i m guessin (and i knew someone w/ a similar setup the 306 w/ edelbrock stuff) probably aout 300-310wheel at most after the tune which means the motor is makin about 360 so thats a real ruff guess[8D]

good luck wit it beat some chevy's for me:)

hey thanks man! havent really had the opportunity to beat up on any chevy's, only a couple of imports. I've only had the car since june, so really looking forward to next year! And i got my rims in the basement, so i cant wait to get them on the car in the spring. Next year is gonna be a blast!

dont guess.....go to a dyno

i was considering getting it towed to the shop and getting it chipped,tuned and dynoed, but theres like a foot of snow on the ground and i live pretty far away from the shop so the tow bill would be pretty big. im just curious thats all.

IMO with those heads you'll be lucky to break 300rwhp.

I had the exact same combo but a 70mm TB and stock heads and made 246rwhp

+1!!

damn. lol. i was gonna see what the guru of hp guessing was gonna throw out there but i was sadly disapointed when i saw that he didnt guess.:(;) but.... i do agree with him, dont guess, dyno it and find out. i will guess you will make anywhere from 1rwhp - 1000rwhp.:D

have you ever ran it at the track? if so theres some calculation (I dont kno exactly what it is) but you use your quarter mile time and speed to roughly tell your HP
